It provides important information on parts and procedures you will need to know to service the Torqmotor.
HY13-1525-M1/US Disassembly and Inspection Low Speed High Torque, Hydraulic Motors TGK Series Place Torqmotor in a vise 1. Place the Torqmotor in a soft jawed vise or similar support, with coupling shaft (12) pointed down and the vise jaws clamping firmly on the sides of the housing (19) mounting flange. SEE FIGURE 1. WARNING WARNING IF THE TORQMOTOR IS NOT FIRMLY HELD IN THE VISE, IT COULD BE DISLODGED DURING THE SERVICE PROCEDURES, CAUSING INJURY. Scribe alignment mark Figure 1 2.
HY13-1525-M1/US Disassembly and Inspection Remove end cover Low Speed High Torque, Hydraulic Motors TGK Series 4. Remove end cover (2). SEE FIGURE 5. Figure 5 Wash & inspect end cover 5. Thoroughly wash end cover (2) in proper solvent and blow dry. Be sure the end cover flow areas are free of contamination. Inspect end cover for cracks and the bolt head recesses for damage. Replace end cover as necessary. SEE FIGURE 6.
HY13-1525-M1/US Disassembly and Inspection Low Speed High Torque, Hydraulic Motors TGK Series Remove manifold 7. Remove manifold (6) and inspect for cracks surface scoring, brinelling or spalling. Replace manifold if any of these conditions exist. SEE FIGURE 9. A polished pattern on the ground surface from commutator or rotor rotation is normal. Remove and discard the seal ring (3).
HY13-1525-M1/US Disassembly and Inspection Low Speed High Torque, Hydraulic Motors TGK Series NOTE Series TGK Torqmotor may have a rotor set with two stator halves with a seal ring (3) between them. Discard seal ring only if stator halves become disassembled during the service procedures. NOTE A polished pattern on the wear plate from rotor rotation is normal. Check rotor vane clearance 9.
HY13-1525-M1/US Disassembly and Inspection Remove thrust bearing Low Speed High Torque, Hydraulic Motors TGK Series 12. Remove rear thrust bearing (11) and retaining bearing washer (10) from top of coupling shaft (12). Inspect for wear, brinelling, corrosion and a full complement of retained rollers. SEE FIGURE 16. Figure 16 Check coupling shaft for rust or corrosion Remove & inspect coupling shaft 12.
HY13-1525-M1/US Disassembly and Inspection Remove shaft seal, backup washer and backup ring Low Speed High Torque, Hydraulic Motors TGK Series 15. Remove shaft seal (16), backup washer (17), and backup ring (18) from TGK Series Torqmotor housing. Discard shaft seal and washers. SEE FIGURE 20. Figure 20 Remove dirt & water seal 16. Remove housing (19) from vise, invert it and remove and discard dirt and water seal (21). A blind hole bearing or seal puller is required.
HY13-1525-M1/US Disassembly and Inspection Inspect housing bearings Low Speed High Torque, Hydraulic Motors TGK Series 18. If the housing (19) assembly has passed inspection to this point, inspect the housing bearings (20) and (13) and since they are captured in the housing cavity, the two thrust washers (14) and thrust bearing (15). The bearing rollers must be firmly retained in the bearing cages, but must rotate and orbit freely. All rollers and thrust washers must be free of brinelling and corrosion.
HY13-1525-M1/US Torqmotor Assembly Low Speed High Torque, Hydraulic Motors TGK Series • Replace all seals and seal rings with new ones each time you reassemble the Torqmotor unit. Lubricate seals and seal rings with clean recommended grease, Parker Gear grease specification #045236, E/M Lubricant #K70M or Mobil Mobilith SHC® 460. A packet of grease (P/N 406018) is included in each seal kit. • NOTE: Complete seal kits are available. SEE FIGURE 25.
HY13-1525-M1/US Torqmotor Assembly Press in outer bearing Low Speed High Torque, Hydraulic Motors TGK Series 2. If the housing (19) bearing components were removed for replacement, thoroughly coat and pack a new outer bearing (20) with clean corrosion resistant grease recommended in the material section. Press the new bearing into the counterbore at the mounting flange end of the housing, using the appropriate sized bearing mandrel such as described in figure 1 which will control the bearing depth to .
HY13-1525-M1/US Torqmotor Assembly Press in dirt & water seal Low Speed High Torque, Hydraulic Motors TGK Series 3. Press a new dirt and water seal (21) into the housing (19) outer bearing counterbore. The dirt and water seal (21) must be pressed in with the lip facing out and until the seal is flush to .020 inches (.51 mm) below the end of housing. SEE FIGURE 28. Figure 28 Place housing assembly into vise 4.
HY13-1525-M1/US Torqmotor Assembly Low Speed High Torque, Hydraulic Motors TGK Series Assemble thrust washers 6. Assemble a thrust washer (14), thrust and thrust bearing bearing (15) and a second thrust washer (14) in that order. SEE FIGURE 33. CAUTION Apply masking tape to shaft Be sure the thrust bearing package is seated in the correct order after assembly of the new shaft seal and new backup washer and backup ring. Figure 33 7.

NOTE Use any alignment marks put on the coupling shaft and drive link before disassembly to assemble the drive link splines in their original position in the mating coupling shaft splines.
HY13-1525-M1/US Torqmotor Assembly Low Speed High Torque, Hydraulic Motors TGK Series NOTE The manifold (6) is made up of several plates bonded together permanently to form an integral component. The manifold surface that must contact the rotor set has it’s series of irregular shaped cavities on the largest circumference or circle around the inside diameter. The polished impression left on the manifold by the rotor set is another indication of which surface must contact the rotor set.
HY13-1525-M1/US Torqmotor Assembly Assemble end cover Low Speed High Torque, Hydraulic Motors TGK Series 19. Assemble end cover (2) over the commutator and in line with the alignment marks on the exterior of the motor. SEE FIGURE 46. Figure 46 Assemble cover bolts 20. Insert the bolts through the end cover until threads of each bolt reach the proper threaded hole of the housing. Hand start each bolt.
Low Speed High Torque, Hydraulic Motors TGK Series HY13-1525-M1/US Final Checks Final Checks • Pressurize the Torqmotor with 100 PSI dry air or nitrogen and submerge in solvent to check for external leaks. Make sure to plug the remaining ports prior to submerging. • Check Torqmotor for rotation. Torque required to rotate coupling shaft should not be more than 50 lb/ft (68 N m).
HY13-1525-M1/US Low Speed High Torque, Hydraulic Motors TGK Series System Maintenance Tips • Adjust fluid level in reservoir as necessary. • Encourage all operators to report any malfunction or accident that may have damaged the hydraulic system or component. • Do not attempt to weld any broken Torqmotor component. Replace the component with original equipment only. • Do not cold straighten, hot straighten, or bend any Torqmotor part.
